Systems and methods for order filling

ABSTRACT

In some embodiments, a method can comprise retrieving an inventory layout of a facility and determining multiple pick lists at the facility. A first pick list for a first user and a second pick list of a second user each comprise a first common item. Receiving a first indication from the first mobile device that the first common item is not available at the facility. Analyzing a first set of rules of a substitute system to locate a first substitute item that is within a first predetermined percentage of a size of the first common item. After analyzing the first set of rules, automatically sending instructions to transfer the first route and the first pick list to the first mobile device.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.15/011,096, filed Jan. 29, 2016. U.S. application Ser. No. 15/011,096 isincorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates generally to systems and methods for orderfilling, and relates more particularly to systems to organize orders,determine order pick lists, and update the order pick lists, and relatedmethods.

BACKGROUND

Currently, orders for items or products placed online through anelectronic commerce website (eCommerce) can be filled by being picked ina warehouse, store, or distribution center. For these orders, picking istypically performed manually by people who are referred to as pickers.Typically, each picker loads a pick list that consists of multipleitems. Once the picker reaches the location of an item on the pick list,the picker either picks the item from the shelf and marked the item as“picked” on the pick list, or if the item is not available, the pickermarks the item as “null” on the pick list. When the picker goes to alocation and that item is not available, the picking time required tocomplete the pick list is unnecessarily lengthened. Furthermore, whenthe same unavailable item is present in more than one pick list for morethan one picker, a lot of time can be wasted. Accordingly, there is aneed for systems and methods to provide better order filling for itemsin a pick list.

In many embodiments, picking items in the same or similarclass comprises picking a class of items as described above together(e.g., produce or freezer items). In some embodiments, not pickingcertain items together in the same pick list can comprise not pickingitems in different classes together (e.g., frozen items with hot cookeditems or cleaning products with groceries). In some or all of theseembodiments, a single order from a single customer can be divided intomultiple pick lists, or can be included in its entirety in a single picklist. Furthermore, when a single picker is fulfilling multiple picklists at a single time, the multiple pick lists can be from the samecustomer or can be from multiple customers.

In some embodiments, method 400 can comprise an activity 425 ofdetermining a first route for a first pick list of the one or more picklists. In some embodiments, the one or more pick lists comprise a route.In many embodiments, the first route can comprise a route through thewarehouse which comprises the shortest distance and/or the shortest timeto complete. In some embodiments, the first route is based at least inpart on the inventory layout of the warehouse and the availability ofthe products on the pick list within the inventory of the warehouse.

In further embodiments, method 400 can comprise an activity 430 ofdetermining a second route for a second pick list of the one or morepick lists. In many embodiments, the first pick list and the second picklist each comprise a first common item of the one or more items. Similarto the first route, the second route can comprise a route through thewarehouse which comprises the shortest distance and/or the shortest timeto complete. In some embodiments, the second route is based at least inpart on the inventory layout of the warehouse and the availability ofthe products on the pick list within the inventory of the warehouse.

Method 400 can further comprise an activity 435 of transferring thefirst route and the first pick list of the one or more pick lists to afirst picker computer, such as picker computer 320 (FIG. 3). In manyembodiments, activity 435 of transferring the first route and the firstpick list of the one or more pick lists to a first picker computercomprises transferring the first route to a first mobile device. Method400 also can further comprise an activity 440 of transferring the secondroute and the second pick list of the one or more pick lists to a secondpicker computer, such as picker computer 321 (FIG. 3).

Continuing with FIG. 4, in further embodiments, method 400 can comprisean activity 455 of updating the first route based at least in part onthe substitute item. In some embodiments, method 400 can update at leasta portion of the one or more pick lists based at least in part on thesubstitute item. In some embodiments, the one or more pick lists can beupdated before the first route is updated. In other embodiments, thefirst route can be updated before the one or more pick lists areupdated, including immediately after the completion of activity 450. Insome embodiments, the first route is updated to include the substituteitem immediately, at the end of the first route, or the substitute itemis inserted in the first route in an efficient manner in order to keepthe first route within a particular distance or time.

In a number of embodiments, method 400 can further comprise an activity460 of updating the second route based at least in part on thedetermination that the first common item is not available. Activity 460can occur after activity 445 and before activity 450, after activity 450and before activity 455, or after activity 455. In some embodiments,activity 460 of updating the second route based at least in part on thedetermination that the first common item is not available comprisesupdating the second route to include the substitute item. In someembodiments, the second route is updated to include the substitute itemimmediately, at the end of the second route, or the substitute item isinserted in the second route in an efficient manner in order to keep thesecond route within a particular distance or time. In some embodiments,method 460 can comprise an activity of determining if the substituteitem can be used as a substitute for the first common item within thesecond pick list for the second route. In many embodiments, the activityof determining if the substitute item can be used as a substitute forthe first common item for the second route can comprise analyzing one ormore rules, such as the substitution rules in method 600 as discussed inFIG. 6 below. Continuing with FIG. 4, the outcome of the substituteproduct determination process within activity 460 for the second picklist might be different from the outcome of the substitute productdetermination process within activity 455 for the first pick list,particularly if the first and second pick lists are for differentcustomers who have different preferences.
